DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

The terminology used herein is for the purpose of describing particularembodiments only and is not intended to be limiting of the presentinvention. As used herein, the singular forms “a”, “an”, and “the” areintended to include the plural forms as well, unless the context clearlyindicates otherwise. It will be further understood that the terms“includes” and/or “including”, when used in this specification, specifythe presence of stated features, integers, steps, operations, elements,and/or components, but do not preclude the presence or addition of oneor more other features, integers, steps, operations, elements,components, and/or groups thereof.

In describing example embodiments illustrated in the drawings, specificterminology is employed for the sake of clarity. However, the disclosureof this patent specification is not intended to be limited to thespecific terminology so selected and it is to be understood that eachspecific element includes all technical equivalents that operate in asimilar manner.

Referencing the drawings, wherein like reference numerals designateidentical or corresponding parts throughout the several views, exampleembodiments of the present patent application are hereafter described.Like numbers refer to like elements throughout. As used herein, the term“and/or” includes any and all combinations of one or more of theassociated listed items.

FIG. 1 illustrates an example view of Global Positioning System (GPS),usable by navigation devices, including the navigation device ofembodiments of the present application. Such systems are known and areused for a variety of purposes. In general, GPS is a satellite-radiobased navigation system capable of determining continuous position,velocity, time, and in some instances direction information for anunlimited number of users.

Formerly known as NAVSTAR, the GPS incorporates a plurality ofsatellites which work with the earth in extremely precise orbits. Basedon these precise orbits, GPS satellites can relay their location to anynumber of receiving units.

The GPS system is implemented when a device, specially equipped toreceive GPS data, begins scanning radio frequencies for GPS satellitesignals. Upon receiving a radio signal from a GPS satellite, the devicedetermines the precise location of that satellite via one of a pluralityof different conventional methods. The device will continue scanning, inmost instances, for signals until it has acquired at least threedifferent satellite signals (noting that position is not normally, butcan be determined, with only two signals using other triangulationtechniques). Implementing geometric triangulation, the receiver utilizesthe three known positions to determine its own two-dimensional positionrelative to the satellites. This can be done in a known manner.Additionally, acquiring a fourth satellite signal will allow thereceiving device to calculate its three dimensional position by the samegeometrical calculation in a known manner. The position and velocitydata can be updated in real time on a continuous basis by an unlimitednumber of users.

As shown in FIG. 1, the GPS system is denoted generally by referencenumeral 100. A plurality of satellites 120 are in orbit about the earth124. The orbit of each satellite 120 is not necessarily synchronous withthe orbits of other satellites 120 and, in fact, is likely asynchronous.A GPS receiver 140, usable in embodiments of navigation devices of thepresent application, is shown receiving spread spectrum GPS satellitesignals 160 from the various satellites 120.

The spread spectrum signals 160, continuously transmitted from eachsatellite 120, utilize a highly accurate frequency standard accomplishedwith an extremely accurate atomic clock. Each satellite 120, as part ofits data signal transmission 160, transmits a data stream indicative ofthat particular satellite 120. It is appreciated by those skilled in therelevant art that the GPS receiver device 140 generally acquires spreadspectrum GPS satellite signals 160 from at least three satellites 120for the GPS receiver device 140 to calculate its two-dimensionalposition by triangulation. Acquisition of an additional signal,resulting in signals 160 from a total of four satellites 120, permitsthe GPS receiver device 140 to calculate its three-dimensional positionin a known manner.

FIG. 2 illustrates an example block diagram of electronic components ofa navigation device 200 of an embodiment of the present application, inblock component format. It should be noted that the block diagram of thenavigation device 200 is not inclusive of all components of thenavigation device, but is only representative of many examplecomponents.

The navigation device 200 is located within a housing (not shown). Thehousing includes a processor 210 connected to an input device 220 and adisplay screen 240. The input device 220 can include a keyboard device,voice input device, touch panel and/or any other known input deviceutilized to input information; and the display screen 240 can includeany type of display screen such as an LCD display, for example. In atleast one embodiment of the present application, the input device 220and display screen 240 are integrated into an integrated input anddisplay device, including a touchpad or touchscreen input wherein a userneed only touch a portion of the display screen 240 to select one of aplurality of display choices or to activate one of a plurality ofvirtual buttons.

In addition, other types of output devices 250 can also include,including but not limited to, an audible output device. As output device250 can produce audible information to a user of the navigation device200, it is equally understood that input device 240 can also include amicrophone and software for receiving input voice commands as well.

In the navigation device 200, processor 210 is operatively connected toand set to receive input information from input device 240 via aconnection 225, and operatively connected to at least one of displayscreen 240 and output device 250, via output connections 245, to outputinformation thereto. Further, the processor 210 is operatively connectedto memory 230 via connection 235 and is further adapted to receive/sendinformation from/to input/output (I/O) ports 270 via connection 275,wherein the I/O port 270 is connectable to an I/O device 280 external tothe navigation device 200. The external I/O device 270 may include, butis not limited to an external listening device such as an earpiece forexample. The connection to I/O device 280 can further be a wired orwireless connection to any other external device such as a car stereounit for hands-free operation and/or for voice activated operation forexample, for connection to an ear piece or head phones, and/or forconnection to a mobile phone for example, wherein the mobile phoneconnection may be used to establish a data connection between thenavigation device 200 and the internet or any other network for example,and/or to establish a connection to a server via the internet or someother network for example.

Thereafter,through its network service provider, the mobile device can establish anetwork connection (through the internet for example) with a server 302.As such, a “mobile” network connection is established between thenavigation device 200 (which can be, and often times is mobile as ittravels alone and/or in a vehicle) and the server 302 to provide a“real-time” or at least very “up to date” gateway for information.

The establishing of the network connection between the mobile device(via a service provider) and another device such as the server 302,using the internet for example, can be done in a known manner. This caninclude use of TCP/IP layered protocol for example. The mobile devicecan utilize any number of communication standards such as CDMA, GSM,WAN, etc.

As such, an internet connection may be utilized which is achieved viadata connection, via a mobile phone or mobile phone technology withinthe navigation device 200 for example. For this connection, an internetconnection between the server 302 and the navigation device 200 isestablished. This can be done, for example, through a mobile phone orother mobile device and a GPRS (General Packet Radio Service)-connection(GPRS connection is a high-speed data connection for mobile devicesprovided by telecom operators; GPRS is a method to connect to theinternet.

The navigation device 200 can further complete a data connection withthe mobile device, and eventually with the internet and server 302, viaexisting Bluetooth technology for example, in a known manner, whereinthe data protocol can utilize any number of standards, such as the GSRM,the Data Protocol Standard for the GSM standard, for example.

The navigation device 200 may include its own mobile phone technologywithin the navigation device 200 itself (including an antenna forexample, wherein the internal antenna of the navigation device 200 canfurther alternatively be used). The mobile phone technology within thenavigation device 200 can include internal components as specifiedabove, and/or can include an insertable card, complete with necessarymobile phone technology and/or an antenna for example. As such, mobilephone technology within the navigation device 200 can similarlyestablish a network connection between the navigation device 200 and theserver 302, via the internet for example, in a manner similar to that ofany mobile device.

For GRPS phone settings, the Bluetooth enabled device may be used tocorrectly work with the ever changing spectrum of mobile phone models,manufacturers, etc., model/manufacturer specific settings may be storedon the navigation device 200 for example. The data stored for thisinformation can be updated in a manner discussed in any of theembodiments, previous and subsequent.

FIG. 2 further illustrates an operative connection between the processor210 and an antenna/receiver 250 via connection 255, wherein theantenna/receiver 250 can be a GPS antenna/receiver for example. It willbe understood that the antenna and receiver designated by referencenumeral 250 are combined schematically for illustration, but that theantenna and receiver may be separately located components, and that theantenna may be a GPS patch antenna or helical antenna for example.

Further, it will be understood by one of ordinary skill in the art thatthe electronic components shown in FIG. 2 are powered by power sources(not shown) in a conventional manner. As will be understood by one ofordinary skill in the art, different configurations of the componentsshown in FIG. 2 are considered within the scope of the presentapplication.

The mass storage device 312contains a store of navigation data and map information, and can againbe a separate device from the server 302 or can be incorporated into theserver 302.

The navigation device 200 is adapted to communicate with the server 302through communications channel 318, and includes processor, memory, etc.as previously described with regard to FIG. 2, as well as transmitter320 and receiver 322 to send and receive signals and/or data through thecommunications channel 318, noting that these devices can further beused to communicate with devices other than server 302. Further, thetransmitter 320 and receiver 322 are selected or designed according tocommunication requirements and communication technology used in thecommunication design for the navigation device 200 and the functions ofthe transmitter 320 and receiver 322 may be combined into a singletransceiver.

Software stored in server memory 306 provides instructions for theprocessor 304 and allows the server 302 to provide services to thenavigation device 200. One service provided by the server 302 involvesprocessing requests from the navigation device 200 and transmittingnavigation data from the mass data storage 312 to the navigation device200. According to at least one embodiment of the present application,another service provided by the server 302 includes processing thenavigation data using various algorithms for a desired application andsending the results of these calculations to the navigation device 200.

The communication channel 318 generically represents the propagatingmedium or path that connects the navigation device 200 and the server302. According to at least one embodiment of the present application,both the server 302 and navigation device 200 include a transmitter fortransmitting data through the communication channel and a receiver forreceiving data that has been transmitted through the communicationchannel.

The communication channel 318 is not limited to a particularcommunication technology.

As shown in FIG. 4A, thenavigation device 200 may be a unit that includes an integrated inputand display device 290 (a touch panel screen for example) and the othercomponents of FIG. 2 (including but not limited to internal GPS receiver250, microprocessor 210, a power supply, memory systems 220, etc.).

The navigation device 200 may sit on an arm 292, which itself may besecured to a vehicle dashboard/window/etc. using a large suction cup294. This arm 292 is one example of a docking station to which thenavigation device 200 can be docked. As shown in FIG. 4B, the navigationdevice 200 can be docked or otherwise connected to an arm 292 of thedocking station by snap connecting the navigation device 292 to the arm292 for example (this is only one example, as other known alternativesfor connection to a docking station are within the scope of the presentapplication). The navigation device 200 may then be rotatable on the arm292, as shown by the arrow of FIG. 4B. To release the connection betweenthe navigation device 200 and the docking station, a button on thenavigation device 200 may be pressed, for example (this is only oneexample, as other known alternatives for disconnection to a dockingstation are within the scope of the present application).

According to embodiments of the present application, a navigation device200 includes a display device 240 to display a point of interest browserincluding multiple point of interest entries and an input device 220 toreceive an input from a user for selecting at least one of the multiplepoint of interest entries. The display device 240 displays mapinformation including a first icon associated with the selected point ofinterest entry. Rich content associated with the selected at least oneof point of interest entry is available to the user via the displaydevice.

According to embodiments of the present application, a navigation device200 includes an input device 220 to receive an input from a user forselecting at least one point of interest entry and a display device 240to display rich content associated with the selected at least one ofpoint of interest entry.

According to embodiments of the present application, a method includesdisplaying a point of interest browser including multiple point ofinterest entries, receiving an input from a user for selecting at leastone of the multiple point of interest entries, and displaying mapinformation including a first icon associated with the selected point ofinterest entry. Rich content associated with the selected at least oneof point of interest entry is available to the user via the displaydevice.

According to embodiments of the present application, a method includesreceiving an input from a user for selecting at least one point ofinterest entry and displaying rich content associated with the selectedat least one of point of interest entry.

According to embodiments of the present application, a navigation device200 includes means for displaying a point of interest browser includingmultiple point of interest entries, means for receiving an input from auser for selecting at least one of the multiple point of interestentries, and wherein the means for displaying displays map informationincluding a first icon associated with the selected point of interestentry. Rich content associated with the selected at least one of pointof interest entry is available to the user via the display device.

According to embodiments of the present application, a navigation device200 includes means for receiving an input from a user for selecting atleast one point of interest entry and means for displaying rich contentassociated with the selected at least one of point of interest entry.

According to another aspect of the present application, a rich contentdocument is a document which includes something more than plain text.Rich content can include one or more of formatting, mixed text andimages, a link to a local document, a link to a document via a networkconnection. The rich content can be included or embedded in a documentor introduced to the document from a different location through amark-up or a description language.

An example display of a rich content document is shown in FIG. 4. Therich content document shown in FIG. 4 includes formatted text. As shown,the document includes different sized text. The text has been bolded,italicized, and/or underlined. Also, the text is shown in differentcolors (only gray scale visible). Text is shown to be left justified andcentered in the display. Text can also be right justified in other richcontent documents. In other displays of the present disclosure,different types of fonts can also be used. As illustrated in FIG. 5,text can be a superscript or a subscript. The text is also shown withstrikethroughs. In other embodiments of the present application, textincluded in a document can be considered rich content by formatting thetext according to the formats listed above and other known to thoseskilled in the art.

In addition to formatted text, rich content can include mixed text andimages, as shown in FIG. 6. Mixed text and images can be described asplacement of images in the body of a text document such that the text isordered around the image without covering and/or changing the substanceof the text. The document displayed in FIG. 6 is a document in which theimages are embedded in the document. When the rich content document isdisplayed on a display device, the document does not call anotherdocument. In other words, the entire rich content of the document livesor is stored in the document.

Alternatively, an image or another document can be included in a richcontent document via a link included in the document. In such a case,the link in the document is rich content. The link can call a documentstored in a memory 230 associated with a navigation device 200. When therich content document is displayed on a display device of the navigationdevice 200, the link calls the document from memory 230 and displays thedocument as defined by the link. The link allows a single stored imagedocument, audio document, and/or video document to be included in anumber of different rich content documents without being stored in morethan one location. Such a link is often referred to as a hyperlink. Inaddition to documents stored in memory 230 associated with a navigationdevice 200, a link can also call documents via a network connection.

For a document called through a network connection, a hyperlink definesa location of a document being called by the link. In such a case, anavigation device communicates with the network and retrieves a documentspecified by the link. The network can be one of several different typesof networks. For example, a network can be one of a local area network(LAN), a metropolitan area network (MAN), a wide area network (WAN), avirtual private network (VPN) etc. A network can be one of severaldifferent sizes depending of the implementation of a navigation device200. The network can be a private network, such that it accessibility islimited to a group of users. As an example, a service provider of anavigation device 200 can setup a private network for its subscribers.Each of the subscribers (a navigation device user) is able to accessdocuments stored on one or more servers hosted by the service provider,such as the mass storage device 312. The navigation device 200 is ableto access a rich content document or a document linked by otherdocuments in the navigation device via the connection to the hostedserver(s).

Alternatively, the network can be connected through an internet serviceprovider (ISP) using a TCP/IP connection. In such a case, a rich contentdocument can be a webpage or a document including a link to a webpage.As illustrated in FIG. 7, an example display of a rich content documentincludes a hyperlink to a webpage for “Victor Hugo.” By selecting thehyperlink, a user of the navigation device 200 opens a webpage definedby the link. In this case, the link is a webpage related to Victor Hugo.

As referenced above, a link can call an image document, an audiodocument, a video document, and other types of documents. In oneimplementation, a video document can be a live video link acquiredthrough a network connection provided through an ISP to a navigationdevice. For example, a live video document can be a webpage including aweb camera view on an intersection at Washington Street and Main Street.When the rich content document is displayed on the display device, thelink calls the web camera video document through the network connectionand displays the virtually live video document of the intersection on adisplay device 240 of the navigation device 200.

Rich content documents can include rich content embedded in a documentor be written such that rich content is described in a document. A linkto another document is one example of description language. Asunderstood by one skilled in the art, description language can be usedto provide rich content as described above. For example, a document canbe written in a mark-up language such as HTML to include specificformats and/or links to other document. When the display device 240 ofthe navigation device 200 displays the rich content document, theinstruction provided in the document dictate how rich content is to bedisplayed. In addition to HTML, another language in which tags specifythe appearance of a document can be used. For example, XHTML (ExtensibleHypertext Markup Language), XML (Extensible Markup Language), or adifferent structure type language may provide rich content to adocument.

As shown in FIGS. 5-8, each example display includes control buttonsalong the right and bottom edges of the display. The buttons are controlinputs for a user of the navigation device 200 on which the display isdisplayed. The control buttons allow the user to adjust the view of thedisplay by scrolling up and down (arrows), paging up and down, going tohome, and going to the end of a rich content document. The appearance ofa control button can be changed to indicate a control button isdisabled. For example, when the end of a rich content document isalready being displayed, the appearance of the scroll down button can begrayed to indicate the scroll down button is disabled, i.e. the documentcannot be scrolled down further.

Along the bottom of the example displays in FIG. 5-8, three buttons aredisplayed, which can receive a user input. The find button allows a userof a navigation device to find a word, a part of a word, or phrase inthe rich content document. When the user selects the find button, a finddisplay prompts the user to enter a search term. After entering thesearch term, the navigation device 200 sequentially finds each inclusionof the search term in the rich content document in response to a userinput. Along with the find button, the bottom of the display alsoincludes a back button and a done button. The back button allows a userto view the previous display. The done button allows the user to exitthe rich content document and return to a menu or prior task, such assome displayed map information.

As shown in FIGS. 9A and 9B, a user of a navigation device can increaseor decrease the size of text displayed on the navigation device.Increasing the text of the document allows the user of the navigationdevice to see text clearly while possibly distracted by otheractivities, such as driving or walking. Unlike text displayed on adisplay device, an image and/or video document is shown as large as theimage is provided to the display device when possible. The image orvideo document is only shrunk when the document includes a format largerthat a display device in a navigation device.

Control of the rich content document also includes the ability to selector highlight text and/or links. As shown in FIG. 8, a user hashighlighted “uitzicht” within the text of the rich content document. Auser can highlight text and/or other rich content within a document forseveral purposes. For example, a user can highlight a word, as shown inFIG. 8, and utilize the find function to find other occurrences of thehighlighted word in the rich content document. Also, a user can select alink to another document. In the example display of FIG. 8, thehyperlink to “Victor Hugo” can be selected by a user to display thewebpage related to Victor Hugo. Additionally, a user can select contentof a document and request map information related to the selectedcontent. For example, a user can select a restaurant link within a richcontent document and request a navigation device 200 to plan a routebetween a current location of the user and the location of therestaurant. Once the route is planned, it is displayed on a displaydevice of the navigation device 200 such that the use can navigate tothe restaurant.

Rich content document can be displayed on navigation device 200 as partof a number of different features. A rich content document can be viewedin response to a user request for the specific document. In such a case,a user can select a rich content document from a document browser. Anexemplary display of a document browser is illustrated in FIG. 10. Thedocument browser can be selected from a menu by a user of a navigationdevice. The document browser allows the user to search and select adocument to be displayed on a display device of the navigation device.The document browser can list available documents and folders or displaythe available documents and folders as thumbnails (illustrated in FIG.10). As shown in FIG. 10, a user can select a folder in the documentbrowser. By selecting a folder, the documents and/or folders containedin the folder are displayed in the display device. The user is able toprovide a further input to select one of the documents and/or foldersdisplayed, and so on. As shown, a title bar is displayed to indicatewhich older or document in the document browser is being displayed.

A user of the navigation device 200 can create a folder and organizedocuments and/or folders by dragging and dropping the documents and/orfolder into/out of a folder. The use can also delete documents andfolders. The document browser also includes a search function such thata user can search for a document. As described above with respect richcontent documents, a document browser can include control button, suchas scroll up and down.

Apart from the document browser, a rich content document can bedisplayed according another feature of a navigation device 200. Forexample, a rich content document can be displayed in the Help, ThirdParty Document, and/or Tourist Information features of the navigationdevice. Rich content documents are viewed in response to featuresdescribed in corresponding applications [include reference to otherapplications here]. In one other feature of a navigation device 200, arich content document associated with a point of interest can bedisplayed.

According to one implementation of at least one embodiment, a method1100 includes step 1102 for receiving an input from a user for selectingat least one point of interest entry. A point of interest can generallybe understood to be a location, place or event that someone may finduseful or interesting. The method 1100 also includes the step 1104 fordisplaying rich content associated with the selected at least one ofpoint of interest entry. An example display of rich content associatedwith a selected point of interest entry is illustrated in FIG. 7, above.The point of interest is the Notre Dame Cathedral.

It should be noted that each of the aforementioned aspects of anembodiment of the present application have been described with regard tothe method of the present application. However, at least one embodimentof the present application is directed to a navigation device 200,including an input device 220 to receive an input from a user forselecting at least one point of interest entry and a display device 240to display rich content associated with the selected at least one ofpoint of interest entry. Thus, such a navigation device 200 may be usedto perform the various aspects of the method described with regard toFIGS. 13-17, as would be understood by one of ordinary skill in the art.Thus, further explanation is omitted for the sake of brevity.

Accordingly to another implementation of at least one embodiment of theinvention, a method 1200 includes step 1202 for displaying a point ofinterest browser including multiple point of interest entries and step1204 for receiving an input from a user for selecting at least one ofthe multiple point of interest entries. The method 1200 also includestep 1206 for displaying map information including a first iconassociated with the selected point of interest entry. As shown in FIG.13, an example display illustrates map information including a firsticon associated with a inn, Tulip Inn.

It should be noted that each of the aforementioned aspects of anembodiment of the present application have been described with regard tothe method of the present application. However, at least one embodimentof the present application is directed to a navigation device 200,including a display device 240 to display a point of interest browserincluding multiple point of interest entries and an input device 220 toreceive an input from a user for selecting at least one of the multiplepoint of interest entries. The display device also displays mapinformation including a first icon associated with the selected point ofinterest entry. Rich content associated with the selected at least oneof point of interest entry is available to the user via the displaydevice. Thus, such a navigation device 200 may be used to perform thevarious aspects of the method described with regard to FIGS. 13-17, aswould be understood by one of ordinary skill in the art. Thus, furtherexplanation is omitted for the sake of brevity.

As shown in FIG. 13, the rich content associated with the point ofinterest entry is available to the user via the display device 240. Theuser provides an input a detail button. When the user provides an inputto the detail button, the navigation device displays rich contentassociated with the POI entry.

A variety of points of interest can be made available to a user of anavigation device. A point of interest can be any one of a governmentoffice, a mountain peak, open parking, a parking garage, a petrolstation, a railway station, a rest area, an airport, a car dealership, acasino, a church, a cinema, a city centre, a company, a concert hall, acourthouse, a cultural centre, a exhibition centre, a ferry terminal, aborder crossing, a golf course, a hospital/clinic, a hotel, a motel, atourist attraction, a mountain pass, a museum, an art gallery, an operahouse, an opera, a place of worship, a post office, a shipping company,a car rental facility, a restaurant, a shop, a mall, a shopping centre,a stadium, a sports arena, a theatre, a tourist information office, azoo, a sports centre, a police station, a firehouse, an embassy, acollege or university, a cash dispenser, a beach, a ice skating rink, atennis court, a water sport, a doctor, a dentist, a veterinarian,nightlife, an amusement park, a library, a care repair/garage, apharmacy, a scenic view, a panoramic view, a swimming pool, a winery, adistiller, a camping ground, a park and recreation area, a conventioncenter, a leisure centre, a marina, a yacht basin, a postcode, alegislator, a lawyer, a solicitor, a counselor, etc.

The rich content can be several different types of informationassociated with the POI entry. The following examples are presented forillustration purposes. The scope of the rich content associated with thePOI entry is not intended to be limited to these explicitly examples ofpoint of interest. Any type of information associated with the POI entrycan be included as rich content.

According to at least one embodiment of the present application, a userof a navigation device 200 may decide to find a restaurant as the usertravels along a planned route. The user can provide an input, which isreceived by the navigation device to commend the navigation device todisplay POI entries along the planned route. The user can specifycriteria for displaying the POI entries as related to the planned route,e.g. within one kilometer of the planned route. As displayed, the POIentries will include a name of each restaurant POI entry. When the userselects a restaurant from the POI entries displayed, the user can selecta detail button (as shown in FIG. 13). When the navigation device 200receives an input at input device 220, the navigation device 200displays information associated with the POI entry for the restaurant.The rich content document can include a menu for the restaurant, anaverage price per entree, a brief description of the restaurant, and/orhours in which the restaurant is open. In some cases, the rich contentcan even include reviews of the restaurant, such as reviews by customersand/or critics. After viewing the details associated with the POI entry,the navigation device can receive a user input to plan a route to thepoint of interest or alter the current planned route to include thepoint of interest. Alternately, the user can select a different POIentry and view associated rich content. The navigation device cancontinue displaying different POI entries until the user finally selectsone of the POI entries or exits the POI browser and/or map informationincluding the POI entries.

In another example, a POI entry can be a movie theatre. When a userselects the detail button, rich content associated with the movietheatre can include names of movies being shown, movie times, and ticketprices. In yet another example, a POI entry is a hotel with rich contentassociated being pictures of the hotel, a description of hotelamenities, rates and availability of rooms at the hotel, etc. In stillanother example, a POI entry can be a fuel/gasoline station with richcontent being hours of operation and current fuel prices at the station.In other implementations, rich content associated with a point ofinterest entry can include hours of operations of a POI entry, times ofevents at a POI entry, pictures of a POI entry, reviews of a POI entry,costs and/or prices at the POI entry, news related to the POI entry,smoking permitted at the POI, or any other useful information related toa POI entry. Rich content can also include copyright information forsome content displayed on the navigation device.

Several other options for selecting a POI entry exist. As illustrated inthe example display of FIG. 14, a user can select a POI entry near theuser's current location, a POI entry along a route (as above), a POIentry in a city, a POI entry near a home location, or a POI entry near adestination. The user can select a POI entry based on these optionsbefore a route is planned, after a route is planned, or without planninga route. In one implementation, a user can specify one or more points ofinterest to be included in a planned route. For example, if a user wasdriving from northern California to southern California, the user couldsearch the POI entries included in a beach category. The user canprovide inputs to the navigation device such that a route planned by thenavigation device 200 includes the beach POI entries selected by theuser. Additionally, a user can plan a route on a navigation device 200based on the location of a point of interest. Once the POI entry isselected, the user can direct the navigation device 200 to display aplanned route to the POI entry. As the user proceeds to the point ofinterest, the navigation device 200 can also display a distance from thepoint of interest on the display device and provide an audible and/orvisible warning when the user is a distance from the point of interestentry, such as one mile.

A point of interest can also be selected from a POI browser. Anexemplary display of a POI browser is shown in FIG. 15. The POI browseris displayed such that a user is able to select a POI category. As shownin the example display of FIG. 15, a user can select from categoriesincluding beach, border crossing, camping grounds, etc. The POI browserincludes scroll up and scroll down control buttons to scroll up/down toview additional categories. As shown in FIG. 16, a user can also inputthe category through keying the spelling or initial letters of acategory in a keypad displayed a navigation device 200. After selectinga POI category, the user is able to select one or more POI entrieswithin the POI category. In one implementation of at least oneembodiment, a user can select all POI entries in a POI categorydisplayed on a navigation device 200. The navigation device 200 thendisplays each of the POI entries sequentially on a display device 240 ofthe navigation device 200. The user steps through the POI entries untilthe user selects one. As the user steps through the POI entries, each isdisplayed along with map information and the option to view rich contentassociated with the POI entry. In another implementation of at least oneembodiment, all of the selected POI entries can be displayed in the mapinformation at one time. Of course, only the POI entries within theboundaries of the displayed map information are displayed on a displaydevice 240 of the navigation device 200. The user is then able toindividually select each POI entry to view rich content associated withPOI entry. In either implementation, the navigation device 200 canfurther received a selection of a POI entry and include processor 210 toplan a route including the point of interest.

An advanced search for a point of interest can also be completed on anavigation device. For example, a user may specify a particular carservice, such as an oil change. The navigation device 200 performs asearch of the POI entries, specifically the associated rich content. Thenavigation device 200, then, displays POI entries that conform with thesearch entered by the user, i.e. oil change services. The user canprovide an input received by the navigation device 200 to select one ormore of the POI entries displayed. When a user selects one of the POIentries, the navigation device can plan a route to the POI entry orinclude the POI entry in an existing planned route.

In a number of implementations of at least one embodiment, a navigationdevice 200 displays map information along with at least one POI entry.The map information generally gives the user an idea the relativelocation of the POI entry as compared to the current location of theuser, some other location, or a planned route. As shown in FIG. 17, whenmap information is displayed along with a POI entry, a first iconassociated with the POI entry is displayed in the map information. Thefirst icon generally indicates the location of the point of interest asincluded in the map information displayed. As shown in FIG. 17, a nameand/or a description of the point of interest can also be included inthe map information or in a title bar displayed along with the mapinformation. Also, a phone device can be included in a navigation deviceto connect with the point of interest. As shown in FIG. 17, a dialbutton in the bottom border of the display invokes a dial function toinitiate a voice call with the point of interest based on contactinformation included in the POI entry.

POI entries are generally stored in memory 230 associate with anavigation device 200. When the POI entries are stored in memory 230associated with the navigation device 200, a user of the navigationdevice 200 can control the view and organization of the POI entries asstore in memory 230. Alternatively, POI entries can be accessed vianetwork communication. When accessed through a network connection, theuser retains some control of the view and organization of the POIentries.

As stated above, when a selected POI entry is included with mapinformation, a first icon is also displayed in the map information. Asshown in FIG. 15, a second icon is displayed in the POI browser. Thefirst icon as shown in FIG. 13 is visibly smaller than the second iconincluded in the POI browser shown in FIG. 15. If both the first icon andsecond icon are displayed from a single image document, the first iconwould have to be stretched to be included in the POI browser or thesecond icon would have to be shrunk to be included in the mapinformation. In either case, stretching or shrinking the icon distortsthe image as displayed. In one implementation of a navigation device, afirst icon and a second icon are stored in different locations, asseparate image documents, in a memory 230 associated with the navigationdevice 200. The image documents are displayed on the navigation device200 without distortion at a size determine by the user and/or navigationdevice.

Also, a user can change the size of an icon. The user can change thesize of an icon as displayed in the POI browser or as included in mapinformation. By changing the size of the icon, a user can differentiatethe POI entry from other POI entries displayed by a navigation device.For example, a user can change an icon associated with a restaurant to asmaller icon in the POI browser based on the user's experience at therestaurant. In another implementation of at least one embodiment, a usercan change the image of an icon associated with a POI entry. An iconrelated to the point of interest can be used instead of the generic iconinitially assigned to the POI entry. For example, a company logo can beused as an icon for a gasoline station rather than the generic gas pumpicon. By allowing a user to change an image and size associated with anicon, icon included in a single category can be different icons, by sizeand/or image.

A user can also organize POI entries included in POI categories bymoving one or more POI entries from one category to another category.Alternatively, the user can copy the POI entries from one category toanother category allowing the POI entry to exist in multiple categories.For example, a POI entry for a hotel can be placed in a category called“Favorite Hotels in New York.” The user can also allow the hotel toremain in the general “Hotel” category such that the POI entry isincluded in more than one category. By allowing a POI entry in multiplecategories, a navigation device 200 ensures that a POI entry is notomitted from a routine category search of a generic category, such aHotel in the example above.

In addition to changing the icon of a POI entry, a user can create a POIentry. For example, if a new hotel opens, a user can create a POI entryfor the hotel. The user can provide the name and contact information ofthe hotel and specify an icon for the hotel. The user can also associaterich content with the POI entry, such as content from a webpagepublicized by the hotel. When a webpage is provided by a hotel oranother third party, the navigation device 200 processes the webpage.The content has to be reduced to an organized and visible. Each subjectin a webpage is aligned and clarified with one or more icons to make therich content attractive and viewable on a displayed device 240 to a userof the navigation device 200. The rich content can be any of thedifferent types of rich content disclosed above. The user can alsoassociate rich content from a different POI entry included and/oraccessible in/by the navigation device 200. Further, a user canassociate rich content with existing POI entries.

In another example, a user of a navigation device 200 can create a pointof interest entry from a received location message, as described incopending application [SMS Location Exchange]. A location message is amessage including a location. When the point of interest entry iscreated by a user, the location provides a position for a first iconassociated with the point of interest entry to be included in the mapinformation. The user can provide further information and rich contentto the entry create from the location message.

In addition to changes made by a user, a navigation device can alsoupdate point of interest entries at an interval to account for changesin the points of interest. For example if a restaurant closes, a user ofa navigation device would prefer up-to-date information regarding theclosing of the restaurant. In one implementation, a navigation devicecan update the POI entries stored in memory 230 associated with thenavigation device 200 automatically. A user of a navigation device 200can, for example, enroll in a program available through a serviceprovider of the navigation device. The enrollment provides the user ofthe navigation device 200 with monthly updates sent to the navigationdevice 200 by the service provider. Other intervals, such as weekly orsemi-annually, can be used.
